Molded strain relief in back shell

Abstract

An electrical connector (1) comprising, an insulative housing block (16), conductive electrical contacts (9) in the housing block (16) connected to corresponding signal wires (2), a conductive ground bus (10) connected to corresponding ground wires (5), plastics material (28) at a rear of the housing block (16) imbedding the ground bus (10) and a portion of the cable (1), and a conductive shell (29) enclosing the plastics material (28).

We claim: 
     
       1. An electrical connector comprising: an insulative housing block, conductive electrical contacts in the housing block connected to corresponding signal wires of a cable, a conductive ground bus connected to corresponding ground wires, plastics material at a rear of the housing block imbedding the ground bus and a portion of the cable, and a conductive shell enclosing the plastics material, arcs of the signal wires and the ground wires being embedded in plastics material. 
     
     
       2. An electrical connector as recited in claim 1, and further comprising: a groove through the plastics material receiving a fastener. 
     
     
       3. An electrical connector as recited in claim 1, and further comprising: a recess opening into a front and a side of the plastics material for receiving a key of the shell. 
     
     
       4. An electrical connector as recited in claim 1, and further comprising: a side of the shell receiving the wires. 
     
     
       5. An electrical connector as recited in claim 1, and further comprising: the plastics material being a shaped block conforming in size and shape to the interior of the conductive shell. 
     
     
       6. An electrical connector as recited in claim 1, and further comprising: when the plastics material is assembled in the shell, the plastics material conforms to an interior size and shape of the shell. 
     
     
       7. An electrical connector as recited in claim 1, and further comprising: the plastics material having been formed into a block having a size and shape conforming to the interior of the shell. 
     
     
       8. A method for constructing a connector comprising the steps of: bending signal wires and ground wires in arcs where the wires enter a housing block holding electrical contacts to which the wires are connected,   imbedding the arcs within fluent plastics material,   molding the plastics material to a shape conforming to an interior of a conductive shell, and   assembling a conductive shell over the plastics material following solidification thereof.   
     
     
       9. A method as recited in claim 8, and further including the step of: exiting the wires through a lateral side of the plastics material, and   covering a back portion of the plastics material with the shell, and   exiting the wires through an opening in a side of the shell.   
     
     
       10. A method as recited in claim 8, and further comprising the step of: laying the housing block and the wires in a cavity of a mold conforming in size and shape to an interior of the shell, and filling the cavity with the fluent plastics material to imbed the wires in a shaped fluent plastic solid.
